AFR Composite Intakes.......

[mlcraven]

Ah, the Tech Section...a never-ending source of fascination. Just checked my pile of amateur books...I have one by Vizard -- bought it years and years ago to figure out how to stab a distributor in an SBC. I think that motor was rebuilt for less than the cost of one of these new-fangled monkey-see-monkey-do composite intakes (back when a dollar would actually buy more than a gallon of gas).

This here is a man that truly gets it, thanks for bringing reality back to the thread!!!.....

He was talking about taillights on the back of a running car, not the ones hanging on the wall in your garage.

Was someone worried about fuel degrading the plastic intakes?

Gas jugs, fuel cells, gas tanks on a plethora of machines... no, I don't think the gas will hurt the plastic.

Exposure to heat over time, or perhaps it's the heating and cooling cycles... that's what I would be concerned with, if anything. Cracking or warping from one of those things. I'd be more worried about the sunlight hitting it when the hood is open than I would be about the gas going through it.

... but I admit I am not "up" on composite materials or their reactions to different elements.

the difference is plastic that flexes, jugs and fuel cells and tanks are all thin walled that still remain flexible. Composite is hard and more brittle. The water necks on the mitsubishit 2.7 are both composite. the temp sending unit is glued into the thing. we had a bad radiator cap that was not releasing at 15 pounds that melted these to leak. Top end air portion of the intake seem like they would be real easy to crack.

Q-16 will go dead in 3 days in a plastic Jug

TC I know you have latched on to this Vizard thing real tight. I have come to see it as you read something then come post a question to relate and argue what you read or cut and paste, truth as I see it is it does not matter, a engine that does not run does not build heat, if it did with a turbo the inlet temp will govern more than the transfered heat from the head. You will lose more power with your mis matched engine than the intake temp difference will be IF it ever sees the fuel in our lifetime. I am done being in your threads like the Buick Guy your just about the Drama

Just remember the only drama is brought on by other members that feel they need to act like they are better than others...... I think by now everyone on this board sees what they are doing....... And what is even worse is when I talk to someone that actually does this stuff for a living and I mention some of the stuff you guys are saying on here and I get this strange look from them with the proverbial "you can believe everything you read on the internet" response...... This happened to me a few times lately, and all I was doing was just relaying what you guys said...... So that is why I decided to start reading Vizard's books, since this guy has been been building championship winning engines for the last 45+ years, the guy is an engineer and understand how engines work, which I don't think a lot of the self proclaimed experts here understand, well other than Dynoroom, and he is the only engine builder on here that has truly impressed me and would have my trust in building an engine, the rest of you guys, like me, are just hacks.........

Like the guy at Chuck's told me, if they have time to hangout on the internet, they probably don't have that much experience in doing it.........

[Bamfster]

And all sarcasm aside, if all the "self proclaimed experts here" "are just hacks", and the "guy at Chuck's" is such an expert, why do you even come here for thoughts on what you are pondering? Just kick it around with those that YOU have determined to be the experts ....

I agree ..... it's just drama .....

[JeffMcKC]

TC show me a Winning engine that Vizard built in a Regular form of racing please. ( Drag, Nascar, Indy, Truck pull, Mud Bog) in the last 5 years. Keep right on Reading 30 year old stuff.

I can't resist.....

The guy at Chuck's got you pegged!

I like to talk cars, I like to get others opinions, that is why I come here......

I think what the guy at Chuck's was getting at is they do this stuff day in and day out for a living and are so busy that they don't have time to hang out on the internet.........Basically they live it and don't have the time to talk about it........ And even amongst my friends that I've told to join this site, they all feel that the internet experts don't know crap....... But then they are the same guys that won't give up the spec on their motors........ Because just like the so called experts here they think they know it all to........ But then some of them have 8 second cars, so maybe they do.............

I live by the moto, that one brain can move houses, while 100 brains can move a mountain........

Or an interesting experiment that Vizard did, they called 4 of the top Cam companies in the country talked to the "so called expert" on the tech line to recommend a cam for a motor that they had already optimized the cam for just to see what cam they would recommend. Each company recommended a different cam, then 4 months later they called the same companies back and got 4 more different cam recommendations, so now they had 8 different cams to choose from and none of them had a 108 LSA, which was the optimum LSA for the cam that made the best power that was in the motor........ That is why I say everyone is a hack, to say one thing works for a motor and assume it works for all motors is wrong, and that is what you get a lot of here.........
